IMPROVEMENT IN ATTACHMENTS FOR SEWING-MACHINES.

Specification forming part of Letters Patent No. 130,914, dated August27, 1872.

' had to the accompanying drawing forming part of this specification, inwhich drawing Figure 1 represents a sectional side view of A thisinvention. Fig. 2 is a plan or top view of the same. The remainingfigures show samples of the work which can be produced by means of myattachment.

Similar letters indicate corresponding parts.

This invention relates, to a device which, when attached to asewing-machine, can be used with great advantage for making hems ofvarious width, for binding, and for bandin g with a plain or with a biasband, for making millinery folds and for cording. My device consistsessentially of an arm, carrying a piece of sheet metal curled up so asto form a rounded back, and open, central mouth, and two folding lips,one on each side of the month, said folding lips being made one with andone without a return bend, and the arm being provided with a slot forthe purpose of attaching the same to a sewing-machine, and adjusting itin the required position in such a manner that theabove-named'operations can be performed with ease and rapidity. With thefolding lips and intermediate mouth of my device I have also combined acordguide, which is secured to one of the folding lips, so that mydevice can also be used with advantage for cording. f

In the drawing, the letters A A*' designate the folding head, which ismade of a piece of sheet metal curled so as to form a closed back, a, anopen mouth, I), and two folding lips, 0. By referring to Fig. 1 of thedrawing it will also be noticed that the lips c of the folding head A*are provided with return bends d, that are not applied to the foldinglips of the head A. Said folding heads are attached each to a slottedarm, B, which is secured, by means of a set-screw, e, to a bracket, 0,of such a construction that the same can be conveniently secured to asewing machine, bringing the head A or A* in the proper position infront of the needle and above the cloth-plate. The bracket which I use,by preference, for this purpose, is described in my patent No. 125,67 4,dated April 16, 1872. With the slotted armB is combined a graduatedgage, D, which is held in position by the set-screw e. The heads A andA*may be attached to one and the same slotted arm, B, at its oppositeends, or they may be secured each to a separate arm. With one of thelips c of the head A is combined a cord-guide, f.

The several operations which can be performed with the folding head Aare illustrated in Figs. 3, 4., 5, 6, 7, 8. In Fig. 3 I have shown theposition of the fabrics in forming a narrow hem, g. In the bight of thefabric may be introduced a cord which is fed in through the cord-guide.

In Fig. 4 I have shown a wide hem, h, which is produced by the foldinghead A, the width of the hem being determined by the gage D.

In Fig. 5 I have illustrated the operation of binding, the band i whichis used for binding being passed through the head with its edgesprojecting into the bight of the folding lips, while the material towhich the binding is to be attached extends into the mouth I) of thehead A. A cord may also be introduced into the bight of the binding.

In Fig. 6 I have illustrated the operation of producing a millineryfold, a band or fabric, j, being passed through the folding head andsewed down upon a skirt or other garment, leaving a bight, k, the extentof which is determined by the gage D. The finished fold is shown in Fig.6*.

In Fig. 7 I have illustrated the operation of securing a plain band, I,upon a skirt or other garment, the band being passed through the foldinghead first at one edge and then at the other. Fig. 7 it shows the bandwhen complete.

In Fig. 8 I have illustrated another method of producing a band out oftwo pieces.

In Fig. 9 I have illustrated the operation of binding with a bias band,m, said bias band bein g made to pass through the folding head A*,which, being provided with return bends d at its folding lips, turns theedges of the band under, as shown, while the fabric to which the band isto be attached extends into the mouth b of the head A In Fig. 10 I haveillustrated the operation of attaching a bias band, a, to a skirt orother fabric.

In Fig. 11 I have illustrated the operation of making a millinery fold,0.

In Fig. 12 I have illustrated the operation of producing a bias band,19, and sewing the same upon a skirt or other garment, the width of saidband being determined by the gage D.

It will also be seen that for most of these operations it is of theutmost importance to leave the cloth plate entirely free andunobstructed, and for this reason I prefer to secure my device to thesewing-machine by means-of a bracket, such as described in my patent No.
